Need help changing a bath/shower drain plug quickly

Hi there, I’m looking for a reliable handyman to replace a faulty bath drain plug. The current plug doesn’t seal properly and water leaks past it, causing slow draining and occasional odors. I have a standard UK bath with a brass or plastic plug and a removable overflow plate. The job involves removing the old plug mechanism, fitting a new, compatible plug and waste, ensuring a good seal, and testing for leaks. Please include basic tools and any parts you might need. I’d appreciate someone who can work efficiently, leave no mess, and confirm everything is functioning before finishing. Preference for a short visit this week if possible.
